Step-by-step explanation:

There are 0.635 centimeters in 1/4 inch.

To convert inches to centimeters using the conversion factor of 2.54.

you can multiply the number of inches by 2.54.

To find the number of centimeters in 1/4 inch, you would multiply 1/4 by 2.54:

(1/4) × 2.54

= 0.25 × 2.54

= 0.635

Therefore, there are 0.635 centimeters in 1/4 inch.

Write each Quadratic function in standard form. The 2 picture is my notes to help with the answer.

Answers

Answer:

33) 4x² + 8x + 1

35) -2x² + 36x - 147

         

Step-by-step explanation:

#33: f(x) = 4(x+1) ² - 3

f(x) = 4(x+1) ² - 3

First Step: Multiply (x+1) (x+1)

(x + 1)² or (x+1)(x+1) is a one real double.

A one real double means that there is only one real solution

(x + 1) (x + 1) = x² + 2x + 1

Second Step: Multiply x² + 2x by 4

4(x² + 2x + 1) = 4x² + 8x + 4

Final Step: Put -3 in the Quadratic Function and do -3 + 4 to get your constant

4x² + 8x - 3 + 4

= 4x² + 8x + 1

#35: f(x) = -2(x - 9) ² + 15

First Step: Multiply (x - 9) (x - 9)

Remember, (x - 9) ² or (x - 9) · (x - 9) is a one real double, meaning that there is only one real solution.

(x - 9) (x - 9) = x² - 18x + 81

Second Step: Multiply by -2

-2 (x² - 18x + 81) = -2x² + 36x - 162

Final Step: Add the constant by 15 in the equation. (Hint: the constant is -162)

-2x² + 36x - 162 + 15

= -2x² + 36x - 147

This is how you convert the function into standard form. Hope this helps.
